“There’s, I believe, over 150,000 disposal wells in the U.S.,” Boling said. “If you look at the number of wells that have been identified with potentially triggering seismicity, it’s less than two-one-thousandths of a percent. I don’t think based on that you could say that industry is doing anything wrong.”
Why do I read that differently than anybody else? Anyway this shows that Arkansas may have just restricted injection at the original site, and that other spots are active. Injection will only be stopped if you have something totally obvious. I still think it can set up large earthquakes if injection is done on a large scale, and there may not be these obvious warnings. Lots of fun yet to come!
